In this chapter I will teach you the notation and Sexy Move.

Before we begin, you need to know the notation. KEEP IN MIND THAT THIS IS A CRUCIAL STEP AS I WILL BE WRITING IMPORTANT ALGORITHMS WITH THE LETTERS.

The letters I will use are:
U (Up)
D (Down)
L (Left)
R (Right)
F (Front)
B (Back)

We also have different versions of these.

1. Row: U D L R F B
2. Row: U' D' L' R' F' B'
3. Row: U2 D2 L2 R2 F2 B2
(There are actually more but I don't want to scare u)

 Row: U2 D2 L2 R2 F2 B2(There are actually more but I don't want to scare u)

1. row
U D L R F B
Keep in mind that when it's a "plain" letter, the layer will be rotated 90* CLOCKWISE, like the picture shows.

2. row
U' D' L' R' F' B'
In the spoken language, we pronounce the little ' as: prime. For instance R' will be pronounced ar prime.
The little' means that you have to rOTATE THE LAYER 90* COUNTERCLOCKWISE. (So, the opposite of where the arrows are pointing in the picture).

3. row
U2 D2 L2 R2 F2 B2
The "2" means that you will have to rotate the layer 2 TIMES THE WAY YOU WANT. YOU JUST HAVE TO ROTATE IT 2 times!

Try this out for yourself!
R U R' U'
(Did you notice this on the book cover?)

The algorithm is called "Sexy Move".
We will use it a lot so make sure to learn it!
